4 Claims.

The present invention relates to fuel oil tank installations, and hasparticular reference to an intake arrangement mounted in the wall of abuilding.

The principal object of the invention is to provide an oil intake boxwhich may be initially installed during construction, or which may beeasily installed in a completed building, and to which the supply pipeto an oil tank and the air vent pipe may be readily attached.

Another object of the invention is to provide a compact oil intake boxwhich is mounted flush with the building wall, and which has no pipesoutwardly connected thereto.

With the above and other objects and advantageous features in View, theinvention consists of a novel arrangement of parts more fully disclosedin the detailed description following, in conjunction with theaccompanying drawings, and more specifically defined in the claimsappended thereto.

In the drawings:

Fig. 1 is a front elevation of the novel intake box, as it appearsinstalled in a brick foundation wall;

Fig. 2 is a vertical section through the intake box; and

Fig. 3 is a rear view thereof.

It has been found desirable to provide a compact fuel oil intake boxwhich is mounted in a wall of a building, and which receives the fueloil nozzle when filling the oil tank, the oil supply line and the ventpipe being secured to the back i of the intake box to eliminateunsightly pipe connections outside the building. I have found itfeasible to arrange a down flow conduit for the oil and a down flowpassageway for the vented air, so that the intake box is of small sizeand is unobstrusive when installed.

Referring to the drawings, the intake box l includes a casing H whichhas generally rectangular walls and may be made of any suitable metal,preferably cast-iron. The face plate [2 of the intake box is preferablyrectangular and has a threaded inflow opening it in the upper portionthereof which is normally closed by a threaded lock nut hi, the openingI3 communicating with an angularly positioned down flow conduit whichleads to a threaded outflow opening IS in the rear wall ll, the openingit having a tutes an air vent chamber 20, the upper portion iii) of thechamber having a threaded air inflow opening 2| in the rear wall 5'! andan associated threaded boss 22 to which the air vent pipe 23 isthreaded, the air passing outwardly from the chamber 20 through air ventslots 2i positioned in the lower portion of the face plate. The lowerwall 25 of the chamber 28 preferably slants downwardly towards the faceplate and the slots 24 to permit free outward flow of rain or the likewhich may enter through the slots 25.

The face plate I2 is preferably provided with an edge flange 26 topresent an attractive appearance when mounted in the building wall, andthe compact design permits dimensioning the box so that it is the heightof two standard building bricks, whereby it is readily inset in newconstructions and is easily installed in old constructions.

The above described construction thus includes a downwardly extendingoil inflow passageway including the inflow opening in the upper portionof the face plate, the angularly disposed conduit, and the outflowopening in the lower portion of the rear plate, and a downwardlyextending air vent passageway which includes the air vent opening in theupper portion of the back plate, the interior hollow chamber of thecasing, and the slotted openings in the lower portion of the face plate.

Although I have described a specific constructional embodiment of theinvention, it is obvious that changes in the size, shape and arrangementof the parts may be made to provide different intake box designs,without departing from the spirit and the scope of the invention asdefined in the appended claims.

I claim:

1. An intake box for fuel oil installations comprising a casing ofhollow formation having a front plate and a back plate, an oil inflowpassageway including an opening in the upper portion of the front plate,an opening in the lower portion of the back plate, and a conduit betweensaid openings, and an air vent passageway including the interior of thecasing, an open ng in the upper portion of the back plate, and anopening in the lower portion of the front plate.

2. An intake box for fuel oil installations comprising a casing ofhollow formation having a front plate and a back plate, an oil inflowpassageway including an opening in the upper portion of the front plate,an opening in the lower portion of the back plate, and a conduit betweensaid openings, and an air Vent passageway including the interior of thecasing, an opening in the upper portion of the back plate, and a slot inthe lower portion of the front plate.

3. An intake box for fuel oil installations comprising a casing ofhollow formation having a front plate, said front plate having an inflowopening in the upper portion thereof, a down flow conduit communicatingat its upper end with the inflow opening, and a threaded opening in therear wall of the casing communicating with the lower end of the downflow conduit, the casing having a threaded air vent opening in the rearwall thereof, said front plate having an air vent slot in the lowerportion thereof.

4. An intake box for fuel oil installations comprising a casing ofhollow formation having a front plate, said front plate having an inflowopening in the upper portion thereof, a down flow conduit communicatingat its upper end 4 with the inflow opening, and a threaded opening inthe rear wall of the casing communicating with the lower end of the downflow conduit, the casing having a threaded air vent opening in the rearwall thereof, said front plate having-an air vent slot in the lower,portion thereof and an edge flange.
